1 Ganglia-groups of neuron cell bodies that lie peripheral to the central nervous system in vertebrates. 2  Bipolar neurons-cell body located near the middle of the axon; characteristic of retinal neurons. 3  Unipolar neurons-cell body lies off to one side of axon; characteristic of sensory neurons.
The principal host for diamonds are rocks formed in the earth's mantle that are known as eclogite and peridotite that are carried to the earth's surface in magmas known as kimberlit e and lamproite.
According to evolutionists and geologists, diamonds were formed about 1â3 billion years ago, thatâs way earlier than any known record of even the Earthâs first land plants let alone coal. Coal, known as a fossil fuel is formed from the dead remains of vegetation like trees, ferns and other plants and life. The formation of coal takes millions of years and can be traced back to 300 to 400 million years ago, but not a billion years.
